 The  jet  grout  columns  extend  from the  founding  elevation  
 to  approximately  one metre  above  the  existing water  
 table. Above this, timber lagging is installed from existing  
 grade during excavation. 
 To  provide  structural  support  for  underpinning  the  
 existing  subway  station,  six 1,500-mm-diameter  structural  
 caissons  will  be  installed  40  metres  deep.  A  welded  wide  
 flange beam and rebar cage will be installed to reinforce the  
 caisson, allowing connection of the underpinning beams to  
 the  caisson  foundations.  CTS will  self-perform  the  entire  
 underpinning operation. 
 Once all of the vertical drilling scope on the south side  
 is  complete,  the  team will  install  a  traffic  deck  consisting  
 of  steel  deck  beams  welded  to  the  piles  within  the  south  
 side secant wall and founding on a temporary strip footing  
 installed on the north side. 
 Lateral bracing welded to each adjacent deck beam will  
 facilitate  load  transfer  while  in  operation.  An  engineered  
 timber  mat  will  be  secured  on  top  of  the  deck  beams  to  
 complete the deck. Traffic will then be diverted to the south  
 side while the surface work begins on the north side. 
 Finally, when the north side is complete, the north deck  
 beam will be bolted to the south deck beam installed earlier,  
 allowing four lanes of traffic to open back up to the public  
 while  excavation  advances  below.  With  excavation  performed  
 by CTS, Keller will install soil anchors, walers and  
 struts to provide lateral support of the excavation. 
 After reaching the underside of the TTC subway tunnel,  
 the team will continue excavation and lateral support work  
 towards  the  west  and  east  ends  of  the  station while CTS
